UNITED STATES PATENT JOSEPH KINTZ, OF BALLARD VALE, MASSACHUSETTS,ASSIGNOR TO HIMSELF AND THE CRAIGHEAD & KINTZMANUFACTURING COMPANY, OFMASSA- CI-IUSETTS.

SUSPENSION-LAMP.

SPECIFICATION forming part of Letters Patent No. 400,856, dated April 2,1889.

Application filed October 4, 1888. Serial No. 287,206. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH KINTZ, of Ballard Vale, in the county ofEssex and State of Massachusetts, a citizen of the United States, haveinvented certain new and useful Improvements in Suspension-Lamps, ofwhich the following is a specification.

My invention relates to that class of suspension-lamps in which aspring-actuated winding-drum is employed to take up and release thesuspensionchains by which the lamp-fixture is hung from the ceiling,this drum having its motion controlled by a springlatch having aconnection extending to the lower portion of the fixture, by which thelatch may be opened when it is desired to raise or lower the lamp.

In the accompanying drawings I have represented at Figure 1, in verticalsection, a suspension-lamp embodying my present improvement, and at Fig.2 an enlarged view of details of the apparatus, as will be hereinaftermore fully explained.

The drawings show a fixture comprising the raising and lowering drum A,supportingchains B B, winding and unwinding from said drum, supports C0, preferably chain, extending from the drum-case downwardly to theshade-ring D, pendent from which are brackets supporting thelamp-fount-cup support E also, I have shown in connection with the druma latch, F, mounted upon a spring, G, within the drum-case, and providedwith an exten sion, II, passing downwardly through the drum-case. Allthe parts thus far described are substantially such as have beenheretofore employed in lamps of this character.

The immediate object of my present invention is to so construct andarrange the connection whereby the spring latch F may readily beoperated from the lower part of the fixture, when it is desired to raiseor lower it, that the same shallbe both graceful in appearance, simplein construction, and easy in operation. I accomplish these results bymeans of the following mechanism: Attached to the lower end of theextension H is a bent rod or cross-bar, I. From the extremities of thiscross-bar I chains K K descend, and their lower extremities areconnected with the upper ends of the arms of a stirrup, L, adapted toconform substantially in its shape to the outline of the lamp-fount-cupsupport and to move vertically within the same. To the lower part ofthis stirrup is attached a downward connection, M, terminating in asuitable finger-graspas, for example, the ring N.

With the construction above described a neat, simple, and convenientdevice is af- 6o forded for operating the spring-latch from the lowerpart of the fixture.

It will be understood that the tension of the spring G, which normallyholds up the latch F in engagement with the drum, also causes thestirrup L to be lifted or held up by reason of the connection throughthe chains and cross-bar. VVheu now it is desired to withdraw the latch,in order to permit the drum to revolve, to raise or lower the fix- 7oture, this may be done by pressing down the ring N, and so long as thisis held downward the fixture may be raised or lowered. (See Fig. 2.)WVhen the pressure upon the ring N is released, the latch F is free tomove upward, under the tension of the spring G, to engage with the drumand stop its revolution, thereby holding the fixture in suspension.

The location of the stirrup L within the lamp-fount-cup support is adesirable feature, because this stirrup is necessarily of fragileconstruction, and being Within the lamp-fountcup support, is therebyprotected from accidental injury by a blow or otherwise. Furthermore,the passages or holes in the upper portion of the lamp-font-cup support,through which the arms of the stirrup move, serve to center it andprevent it from turning, and thus, the lamp-fount-cup support itselfbeing utilized for this purpose, no addio tional guides for the stirrupneed be provided.

I am aware of the structures described and shown in United StatesLetters Patent No. 285,381, dated September 26, 1883, and No. 311,224,dated January 27,1885, and disclaim as of my invention anything thereinshown or described.

I claim In a suspension-lamp of the character described, thecombination, with the mechanism I00 which controls the motion of theraising and lowering drum, of a hollow lamp-fount-cup support, E, astirrup, L, located and vertically movable therein and having its upperportions passing through the upper portion of the lainp-fount-eupsupport,2t finger-grasp,N, attached to the lower part of the stirrup,and connections K, extending upwardly from the upper ends of the saidstirrup and attached to the extremities of a C1OSSbL1,I, connected withthe drum-controlling latch, all substantiztlly as set forth.

In testimony whereof I have hereunto sub- 1o scribed my name this 25thdayof September A. D. 1888.

JOSEPH KINTZ.
